"Since our conversation last night I've been carefully weighing matters. The motive of the cruel and ingenious assassination of your friend Nicholson is perfectly plain. Harford knew that there was a will in existence, for now I recollect Mr Edgecumbe, after getting me to make it, told me that he had revealed its provisions to his friend. They are that his daughter should inherit the whole of his very substantial fortune, but in the event of her death while unmarried it was to go to Harford himself, in recognition of his friendship and of his kindness to Miss Asta. Now if Nicholson had married her, the money would have passed beyond his control. Therefore, aided, no doubt, by Earnshaw and his wife, they killed him by a method which fully bears out my estimate of the craft and cunning of my client's late partner. Edgecumbe, not long before his death, had somehow become aware of the existence of the huge spider, kept as a pet, and having suspicions as to what use it might be put to, warned you of it with his last effort. Nicholson, against whom it is more than probable an unsuccessful attempt was made one night while sleeping at the Hall, also discovered Harford's secret. He intended to reveal it to you, but was attacked, and succumbed before he could call upon you. Harford next feared lest you might propose marriage to his ward, hence the fact that he carried his pet to the Continent with him, and you saw the terrible `Hand' and narrowly escaped its fatal grip on that night in the old French inn. Yes, Mr Kemball," Fryer added, "depend upon it that Harford played his last card when he allowed the terrible spider to pass into Miss Asta's bedroom. He intended that she should die, and that Arnold Edgecumbe's fortune should be his--a plot which would, alas! have been successfully accomplished, had your suspicions not been providentially aroused." A sudden call from the locksmith caused us to return hastily to Fryer's room, and there we saw that the top of the ancient cylinder had been filed entirely off. "There's something inside, sir," said the man, addressing the solicitor. "Perhaps you'd like to take it out yourself." And Mr Fryer drew forth a portion of an ancient leather thong, attached to which was a large old seal of clay with an ancient Egyptian cartouche impressed upon it. CHAPTER THIRTY FOUR. WHAT THE CYLINDER CONTAINED. Mr Fryer then took the cylinder in his hand, and with eager fingers first drew forth a piece of modern paper about six inches long, folded lengthways many times. When he opened it I saw that parts of it were brown as though scorched, while it bore at its base one of the long green stamps used in the Consular service, obliterated together with attesting signatures. At a glance he recognised its nature.
